RadioGroup listener dont work

I have a Fragment that displays a Dialog.
Inside that Dialog there is a RadioGroup.
I tried to create a listener to this RadioGroup, but i didn't successed.
Fragment --> Dialog --> RadioGroup
I tried four ways:
OnCheckedChangeListener on RadioGroup.
OnClickListener on RadioGroup.
OnCheckedChangeListener on RadioButton.
OnClickListener on RadioButton
No one worked.
Here is my code:
The Dialog - layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<RadioGroup
android:id="#+id/bS_rg"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:orientation="vertical">
<RadioButton
android:id="#+id/r_id"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="ID"
android:textSize="24sp" />
<RadioButton
android:id="#+id/r_title"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="Title"
android:textSize="24sp" />
<RadioButton

<RadioButton
android:id="#+id/r_author"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="Author"
android:textSize="24sp" />
</RadioGroup>
<AutoCompleteTextView
android:id="#+id/c_bSearch"
android:layout_width="278dp"
android:layout_height="72dp"
android:singleLine="true"/>
</LinearLayout>
The Fragment - layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Remove selected dynamic checked items from listview

Here, in a listview I have added a custom row in which Checkbox and EditText are there and with a add button I just add multiple views to my listview. Adding is working perfectly but when it comes to removing part the checked items are not removing and apart from that suppose I selected two items, then two items from last deleted. I don't know whats going on with my code please help me.
Here is my code:
MainActivity.java
public class MainActivity extends AppCompatActivity {
AdapterCustom customAdapter;
ArrayList<String> stringArrayList;
ListView listView;
ArrayList<Integer> listOfItemsToDelete;
AdapterCustom.ViewHolder item;
int POS;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listOfItemsToDelete = new ArrayList<Integer>();
stringArrayList = new ArrayList<String>();
LinearLayoutManager layoutManager
= new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
listView = (ListView) findViewById(R.id.list_item);
customAdapter = new AdapterCustom(MainActivity.this, R.layout.main, stringArrayList);
}
public void addItems(View v) {
stringArrayList.add("");
listView.setAdapter(customAdapter);
customAdapter.notifyDataSetChanged();
}
public void removeItems(View v) {
if (listOfItemsToDelete.isEmpty()) {
Toast.makeText(getBaseContext(), "No items selected.",
Toast.LENGTH_SHORT).show();
} else {
Log.i("Delete Pos", POS + "");
if (!listOfItemsToDelete.equals("")) {
for (int j = 0; j < listOfItemsToDelete.size(); j++) {
stringArrayList.remove(listOfItemsToDelete.get(j) - j);
customAdapter.notifyDataSetChanged();
}
}
}
}
AdapterCustom.java
public class AdapterCustom extends ArrayAdapter<String> {
Context context;

this.context = context;
this.stringArrayList = arrayList;
positionArray = new ArrayList<Boolean>(stringArrayList.size());
for (int i = 0; i < stringArrayList.size(); i++) {
positionArray.add(false);
}
activity = new MainActivity();
}
#Override

return stringArrayList.size();
}
#Override

return stringArrayList.get(position);
}
#Override

You only remove the item from the array. Try removing the item also from the list view adapter with adapter.remove(itemPosition);

What does mean
- j
in this code:
for (int j = 0; j < listOfItemsToDelete.size(); j++) {
stringArrayList.remove(listOfItemsToDelete.get(j) - j);
customAdapter.notifyDataSetChanged();
}
?
I think that:
for (String itemToRemove:listOfItemsToDelete) {
stringArrayList.remove(itemToRemove);
}
customAdapter.notifyDataSetChanged();
listOfItemsToDelete.clear();
would be appropriate.

after selecting the checkbox all listview item checkbox not selected

After selecting the header checkbox all listview item checkbox not selected.
Selected listview checkbox items are not moved from list1 to list2.

Please find the below screenshots
If I select header checkbox(select all), only first five rows are selected
Remainig rows are not selected
If I select row 2 and row 3 and click on add I got wrong output(refer last screenshot)
row 2 and row 4 are added in list2 (but correct output is row 2 and row 3 should be added) after clicking on add all the checkboxes should be unchecked.
Please help me thanks in advance.

Hope this help!

Because after checked you are adding on the array that contain in adapter and on scrolling it will refresh. So you should use interface here after checked or unchecked you should add status in main class and then notify your adapter and invalidate your listview.

Button click event with Custom List view

I have two button at bottom i.e after listview ends.
I am using a custom listview which display list items with alternate colors.
how to set setOnClickListener for both button at bottom?
public class PieMainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mRes = getResources();
new Random(new Date().getTime());
solbtn = (Button)findViewById(R.id.solution);
String recive ;
Bundle b = getIntent().getExtras();
final int piewrong=b.getInt("piewrong");
final int pieright=b.getInt("pieright");
final int pieunclick=b.getInt("pieunclick");
setContentView(R.layout.piechart_result);
recive = pieright+"/20";
mPie.setUnit(recive);
data1 = new ArrayList<String>();
fillData() ;
listtotal =getIntent().getStringArrayListExtra("listtotal");
timeuse =getIntent().getStringArrayListExtra("timeused");
adapter1 = new ListAdapter(this, data1, listtotal,timeuse);

((TextView) view.findViewById(R.id.duration)).setText(timeused.get(position));
return view;
//String.valueOf(value);
}
}

So these buttons are not part of your ListView? Well, than in your onCreate do something like:
solbtn = (Button)findViewById(R.id.solution);
solbth.setOnClickListener( toolbar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
yourMethod();
}
});
And the same goes for the second button.
Or you can make your Activity implement View.OnClickListener, after doing this you can set your click listeners like this:
//this two lines in your OnCreate
button1.setOnClickListener(this);
button2.setOnClickListener(this);
//somewhere later in the code
#Override
public void onClick(View v) {
//do something
}

Just add the clickListeners in your onCrete() method:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
.....
solbtn = (Button) findViewById(R.id.home);
homebtn = (Button) findViewById(R.id.solution);
solbtn.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// do stuff for solution button
}
});
homebtn.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// do stuff for home button
}
});
.....
}

How to get value of all selected radio buttons from all the views in sliding Fragment

I have three views in sliding Fragment with Survey Questions having dynamic radiobuttons (the layout for all views are same, i am just repeating). I can get the data of selected radiobuttons from one screen, but how can i get the data of all selected radiobuttons from all screens ? Below is my working code
FragmentActivity.java
